Protozoa, Fungi Worksheet featuring three protozoan organisms and questions about their movement, type, and classification.

Problem Analysis:

The worksheet provided is about protozoa and fungi. The task involves identifying the characteristics of different organisms (A, B, and C) based on their images and classifying them accordingly. Additionally, there are questions about the general characteristics of protists and examples of unicellular and multicellular algae.

Step-by-Step Solution:

#### 1. Identifying Organisms A, B, and C:

- Organism A:
- Image Description: This organism has a pseudopod-like structure, which is characteristic of amoebas.
- Movement: Amoebas move by extending and retracting their pseudopods.
- Type of Protozoan: Amoeba.
- Classification: Unicellular, Eukaryotic, Heterotrophic.

- Organism B:
- Image Description: This organism has a flagellum, which is used for movement.
- Movement: Moves by means of a flagellum.
- Type of Protozoan: Flagellate (e.g., Euglena or Trypanosoma).
- Classification: Unicellular, Eukaryotic, Heterotrophic/Autotrophic (depending on the specific type).

- Organism C:
- Image Description: This organism has cilia covering its surface.
- Movement: Moves by means of cilia.
- Type of Protozoan: Ciliate (e.g., Paramecium).
- Classification: Unicellular, Eukaryotic, Heterotrophic.

#### 2. General Characteristics of Protists:

- Unicellular or Multicellular: Protists are primarily unicellular.
- Prokaryotic or Eukaryotic: Protists are Eukaryotic.
- Autotrophic or Heterotrophic: Protists can be either autotrophic or heterotrophic, depending on the type.

#### 3. Major Divisions of Protists:

Protists are typically divided into three major groups based on their mode of locomotion and other characteristics:

- a. Amoebozoa:
- Characteristics: Move using pseudopods.
- Example: Amoeba.

- b. Mastigophora (Flagellates):
- Characteristics: Move using flagella.
- Example: Euglena.

- c. Ciliophora (Ciliates):
- Characteristics: Move using cilia.
- Example: Paramecium.

#### 4. Examples of Unicellular and Multicellular Algae:

- Unicellular Algae:
- a. Diatoms (e.g., *Phaeodactylum tricornutum*)
- b. Dinoflagellates (e.g., *Gonyaulax*)
- c. Chlorella

- Multicellular Algae:
- a. Seaweed (e.g., *Laminaria* or Kelp)
- b. Spirogyra (a filamentous green alga)
- c. Ulva (commonly known as sea lettuce)

Final Answers:

#### Organism Identification:
- Organism A:
- Moves by means of: pseudopods
- Type of protozoan: amoeba
- Is a(n): unicellular, eukaryotic, heterotrophic

- Organism B:
- Moves by means of: flagellum
- Type of protozoan: flagellate
- Is a(n): unicellular, eukaryotic, heterotrophic/autotrophic

- Organism C:
- Moves by means of: cilia
- Type of protozoan: ciliate
- Is a(n): unicellular, eukaryotic, heterotrophic

#### General Characteristics of Protists:
- Circle: Unicellular, Eukaryotic, Heterotrophic

#### Major Divisions of Protists:
- a. Amoebozoa → Moves using pseudopods.
- b. Mastigophora (Flagellates) → Moves using flagella.
- c. Ciliophora (Ciliates) → Moves using cilia.

#### Examples of Algae:
- Unicellular Algae:
- a. Diatoms
- b. Dinoflagellates
- c. Chlorella

- Multicellular Algae:
- a. Seaweed (Kelp)
- b. Spirogyra
- c. Ulva
